Yep, I am sure that the different government entities over looked that one. Or maybe it is a conspiracy.

Look, in order to get the type of national security clearance President elect Obama now holds requires the tightest of scrutiny.

If the NSA, FBI, CIA, DOJ, etc., etc., etc. are satisfied, then so am I.
For anyone to believe that a persons place of birth has not been established after that type of scrutiny, well, I am sorry, but you need to re-evaluate why you believe what you believe.
